Only 45 percent of 3G capable devices have a valid 3G subscription in India, Nokia Company said on Wednesday.

According to a study by the company, India has witnessed 26 percent growth in 3G subscription during the last six months, while 3G penetration in India was only 24.59 percent, which speaks of a huge opportunity for telecom operators.

As per the report, one in every four Indians has a capable 3G device (supporting 2,100 MHz band), while 3G subscribers today are only at 100 million.

Among them, there are 15.58 percent (144 million) 3G phone penetrations on 900 MHz. This can help boost 3G services in India in the 900 MHz band in future.

There is a huge potential in non-metro cities as well. Mumbai has the highest penetration of 3G, followed by Delhi.

As per the study, the top 5 circles as per 3G device penetrations are Mumbai, Delhi, Kerala, Punjab and Kolkata.

West Bengal, Bihar, Uttar Pradesh (East), Assam and Odisha have the lowest 3G phone penetration. However, due to a large subscriber population, there is an immense potential for 3G in these states.

"A significant population of subscribers today has 3G enabled devices which are still untapped. There is a possibility of 4G leap-frogging 3G in terms of new subscriber addition. Since the price point of Long-Term Evolution (LTE) devices are expected to come done from Rs.8, 000 levels to around Rs.4, 000 levels in next few months," head of technology at Nokia Networks, Amit Marwah, said in a statement.

The report further stated that LTE device penetration is still low at 1.61 percent.

It said 1,800 MHz enabled LTE devices leads with 1.45 percent (13.3 million) followed by 2,100 MHz enabled devices at 1.2 percent.

"India today has about 14.8 million capable subscribers who are using 4G phones, but 4G subscriptions are significantly lower. Mumbai, Delhi, Kerala Punjab, Karnataka have LTE device penetration (on LTE 1800/ FD LTE) over two percent of their subscriber base," the statement said.
